Driving
■Driving on a downhill
On declines, there may be case where the vehicle shifts down automatically to obtain
engine braking. As a result of the downshifting, the engine speed may increase.
■Second start mode automatic deactivation
Second start mode is automatically deactivated if the engine is turned off after driving in
second start mode.
■S mode
When the shift range is 5 or lower, holding the shift lever toward “+” sets the shift range to
6.
■AI-SHIFT
AI-SHIFT automatically shifts the gear to the suitable position according to driver perfor-
mance and driving conditions.
AI-SHIFT automatically operates when the shif t lever is in the D position. (Shifting the
shift lever to the S position cancels the function.)
■When driving with the cruise control or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.
( → P. 224, 227)
■Shift lock system
The shift lock system is a system to prevent accidental operation of the shift lever in start-
ing.
The shift lever can be shifted from P only when the engine switch is in the IGNITION ON
mode and the brake pedal is being depressed.

■If the shift lever cannot be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brake pedal, there may be a prob-
lem with the shift lock system. Have the vehicle inspected by your Lexus dealer, immedi-
ately.
The following steps may be used as an emergency measure to ensure that the shift lever
can be shifted.
Releasing the shift lock:
Set the parking brake.
Turn the engine switch off.
Depress the brake pedal.
■If the “S” indicator does not come on even after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have the vehicle
inspected by your Lexus dealer immediately.
(In this situation, the transmission will operate in the same manner as when the shift lever
is in D.)
■Downshift restriction warning buzzer (S mode)
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, downsh ifting may not be possible even when the
shift lever is operated. (A buzzer will sound twice.) Pry the cover up with a flathead screwdriver
or tool.
Press the shift lock override button.
The shift lever can be shifted while the button
is pressed.

CAUTION
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid, resulting in an
accident.
■To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to set the parking brake and
depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal when the
shift lock override button is pressed and the shift lever is shifted out of P, the vehicle
may suddenly start, possibly leading to an acc ident resulting in death or serious injury.

GX 460 _O M_ OM6 0F 6 8U _(U )4-3. Operating the lights and wipers
■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically whenev
er the engine is started and the parking
brake is released with the headlight switch off (type B only) or in the “AUTO” position.
(Illuminate brighter than the parking lights. ) Daytime running lights are not designed for
use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to turning on the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help improve fuel economy.
■Headlight control sensor
■Automatic light off system
●When only the tail lights are on: All lights turn off if the engine switch is turned to
ACCESSORY mode or turned of f and the driver’s door is opened.
●When the headlights are on: All lights turn off 30 seconds after a door or the glass
hatch is opened and closed.
To turn the lights on again, turn the engine switch to IGNITION ON mode, or turn the
light switch off once and then back to or .
■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■If the automatic headlight leveling system warning light flashes
It may indicate a malfunction in the system. Contact your Lexus dealer.
■Welcome lighting
If the headlight switch is turned to AUTO an d the surrounding area is dark, unlocking the
doors using the smart access system with push-button start or wireless remote control
will turn the parking lights an d tail lights on automatically.
■Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: →P. 5 9 4 )
The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than ne
cessary when the engine is not running.
